Patented Oct. 26, 1937 UNITED STATES PATENT OFFlE PIPE This invention relates to smoking pipes, and has for its principal object to provide a new and improved construction of a pipe in which there is incorporated in a relatively small pipe a long passage for the smoke, whereby a cool smoke is obtained.

Another object of the invention is to provide the bowl portion of the pipe with a plurality of communicating passageways to provide a circuitous passage, thereby to considerably lengthen the distance which the smoke must traverse from the bowl to the mouth-piece of the pipe, and which passageways are so arranged that they may be readily bored to furnish communication with the bottom of the bowl by means of an ordinary drill, both passages being readily accessible through the opening which serves for connection to the bowl of the mouth-piece. This construction also enables the smoke passages to be readily cleaned by the use of an ordinary pipe cleaner.

A further object is to incorporate with the stem, or mouth-piece'of the pipe, a tube, preferably of metal, which projects into one of the passages formed in the stem portion of the bowl to define with such passage an additional circuitous path for the smoke to traverse.

Although I am aware that it is not broadly new to provide smoking pipes with various means to define a circuitous passage for the smoke, such pipes as heretofore constructed have, as far as I am aware, been of rather complicated construction which are either very difficult to manufacture, or were of cumbersome construction with a resulting unattractive appearance. It is, therefore, a further object of the present invention to provide a smoking pipe with a circuitous smoke passage of simple construction that can be readily manufactured but yet, withal, is of neat, compact and attractive appearance.

The above and other objects will appear more fully from the following, more detailed description, and by reference to the accompanying drawing forming a part hereof, wherein:

Fig. l is a perspective view of one form of pipe constructed in accordance with the principles of the present invention, and

Fig. 2 is a central longitudinal section through the pipe shown in Fig. 1.

As shown in the drawing, the pipe comprises a bowl member I0, having the usual bowl I I, which serves as a receptacle for the tobacco. The member I0 is also provided with a stem portion I2, which as shown, is sufficiently thickened to provide sufficient material to enable a main passageway I3 and an auxiliary passageway I4 to be Birmingham, Mich.

drilled into the stem. The passageway I3 is closed, as shown, at its inner end, and its outer end communicates with a counterbore I5 in which is adapted to be engaged the reduced end It or" the mouth-piece IT.

The mouth-piece I1 is provided with the usual bore, or passage I8, and has suitably secured to its inner end a small tube I9 which preferably is of metal and which tube projects into the main passage I3 and terminates short of the inner closed end thereof.

. The auxiliary passage I4 communicates at one end with the bowl II adjacent the bottom thereof, and at its other end with the bottom of the main passage I3 adjacent to the counterbore I5.

As will be seen from an inspection of the drawing, and the foregoing description, the construction results in the provision of a long, circuitous passage for the smoke from the bowl to the mouth-piece, the smoke being drawn through the auxiliary passage I4 to the rear end of the main passage I3, from which it flows forwardly through said main passage to be drawn through the metal tube I9 and passageway I8 to the smokers mouth.

It will be noted the construction is such that the auxiliary passage I4 is a straight passage and arranged at such an angle as to be readily accessible from the counterbore I5 of the stem portion I2 of the member I0. Consequently the auxiliary passageway I4 can be readily drilled with a small, straight drill directly from the open end of the counterbore I5. Likewise, the main passageway I3 is a straight passage that can also be drilled straight in from the counterbore I5. As both passages I3 and I4 may be said to open directly into the counterbore I5, these passageways may be readily cleaned by removing the mouth-piece I8 and by the use of any ordinary pipe cleaner.

The tube I9 preferably being made of metal, serves to insure the condensation of any moisture on this tube and prevents such moisture from finding its way to the auxiliary passage I4 and thence to the bowl of the pipe.

It will be seen that a pipe constructed as above described will have a smoke passage nearly twice the distance of a pipe of conventional design of about the same dimensions, and that the cooling effect of a very long stemmed pipe is obtained in a pipe of small, compact size that may be readily carried in the users pockets.

' It will also be noted that the construction is such that any saliva which might flow into the passage I8 will be obstructed by the closed end of the main pasage I3, and as the pipe in use would ordinarily be held in the smokers mouth at a While I have shown the invention embodied in a pipe having a straight stern, it will be readily understood that the invention is not limited to a pipe of the particular configuration shown in the drawing, but that the invention is readily applicable to pipes having curved stems, or bowls of any desired shape or size.

It will also be seen that the present type of construction is readily applicable to bowls constructed of any desirable material, such as briar, meerschaum, corn cob, or any of the usual materials used for the construction of pipes. Likewise the simplicity of the mouthpiece construction enables any of the well known and desirable materials, such as amber, to be used for the construction of the mouth-piece.

Although I have shown and described the main passage I3 as provided with a counterbore l5, it will be understood that the use of such counterbore is not essential but that the main passage may be made of sufliciently large diameter to receive the mouth-piece directly.

I claim:

In a smokers pipe, a bowl portion having a tobacco receiving chamber therein and a thick stem portion extending substantially at right angles to said chamber, the upper and lower walls of said stem portion merging with said bowl portion and converging towards the end of said stem portion to form a bit receiving end of substantially circular cross sectional configuration, said bit receiving end being counterbored and said stem portion having an enlarged main bore extending substantially perpendicular to said chamber, in axial alignment with said counterbore substantially in parallelism with the upper wall of said stem portion and having a closed inner end, and an auxiliary bore of small diameter extending at an acute angle to and below said main bore substantially in parallelism with the lower wall of said stem portion with its inner end communicating-with the lower end of said chamber and its outer end communicating with said main bore adjacent to said counterbore and so that the prolongation of its axis intersects the center of said counterbore at the outer end thereof. v
